title: Correction of mandibular prognathism by mandibular setback and advancement genioplasty.
abstract: The goal of surgical-orthodontic treatment of mandibular prognathism is to achieve maximum function, esthetics and stability. These objectives were achieved in 10 adults who manifested a specific type of mandibular prognathism. The patient group under study, who manifested a relatively contour deficient chin and prominent lower lip, and class III malocclusion, was treated by orthodontics and mandibular setback in concert with advancement genioplasty. The advancement genioplasty technique was accomplished by maintaining as much soft tissue pedicle as possible to the repositioned chin. A near one-to-one ratio of soft tissue-to-osseous change was achieved in the patient group under study with the use of the described genioplasty technique in combination with mandibular setback by intraoral vertical ramus osteotomies.
